Bug or feature? sum(c(a, b, c)) != (a + b + c)
Greetings all,
I'm porting an algorithm from MATLAB to R, and noticed some minor
discrepancies in small decimal values using rowSums and colSums which
are exacerbated after heavy iteration and log space transformation.
This was rather perplexing as both programs claimed and appeared to use
the IEEE 754 standard for floating point arithmetic (confirmed with
manual basic operations). After some tracing and testing, I've managed
to isolated a minimal work...

StoryRunner docs/guidance
Hi all,
Are there any plans for better documentation for the new StoryRunner
feature? I tried to use it today (with Rails), and had a hard time
getting my head around whether I was doing it "right" and exactly what
things are appropriate to test at that level (this might be exacerbated
by the fact that I''ve never really used integration testing that much).
A full example of testing a Rails controller would be extremely useful
to me.
Thanks,
Jon

manipulating "by" lists and "ave()" functions
dear R wizards---more ignorance on my part, exacerbated by too few
examples in the function documentations.
> d <- data.frame( id=rep(1:3,3), x=rnorm(9), y=rnorm(9))
Question 1: how do I work with the output of "by"? for example,
> b <- by( d, d$id, function(x) coef(lm( y ~ x, data=x ) ))
> b

Psych package: fa.diagram, how to re-arrange layout so numbers do not over-write each other
...ent factors predict the 37 items in a psychological battery. However, the display on the screen has very large font size for the coefficients of the relationship between the 11 factors and the 37 items, so the numbers overlap and are therefore illegible. When I output this to a pdf the problem is exacerbated even further (see attachments). I tried to use cex=0.8 and cex=0.4 in the pdf argument but it made no difference - what can I do?
The code I used is:
fa.diagram(fa.11factors.rawdata)
# Start PDF device driver to save output to fa_diagram.pdf

c't listening test: Ogg problem at 128kbps
...Real) had frequency response problems, AAC had
background noise, and WMA lacked impulse response. So I don't think I
should be concerned about my hearing...
At 128kbps, however, most of the frequency response problems were gone
-- except this time, I picked Ogg as the worst, based on an overly
exacerbated treble. Others were still noisy and lacked impulse detail,
but Ogg/Vorbis was the one I decided first was definitely not close to
the original. Listening to it again, I can confirm the difference I
heard, although maybe I wouldn't put it in last place this time.
The passage I based the Ogg/Vo...

Creating "%d/%m/%Y %H:%M:%S" format from separate date and time columns
...startt<- strptime((paste(data2$V4, data2$V5)), "%d/%m/%Y %H:%M:%S")
This executes without any warnings, but returns a full column of NA
values. It would be great to fix this, and then to know how to
correctly add column V6 as seconds to the resulting column.
The problem is further exacerbated by an error with dput() with this
data. It's a large dataset of over 9000 rows, and when I call:
dput(head(data2,50))
It returns dput(), but for all the data (i.e. not the first 50 rows).
This of course does not fit on the workstation screen and therefore I
cannot find out what class it has...

should_receive_chain
Do you often find yourself doing this:
active = double(''active'')
active.should_receive(:first)
users = double(''users'', active: active)
account.should_receive(:users).and_return(users)
for this:
account.users.active.first
?
Of course, we could use stub_chain, but that doesn''t let us know
*where* the chain broke.
Would you like to do this?

[LLVMdev] Minor FileCheck proposal: CHECK-UNIQUE for labels to improve error messages
...ges are
not very helpful in cases where a check is incorrect but matches
something that occurs in a later block: the checker continues assuming
that the matched line is correct (no matter how much farther ahead it
occurs) and then provides a misleading error message some time later.
The problem is exacerbated if many similar tests are put in one file,
since many checks can end up succeeding with unintended matches before
something ends up failing.
I propose a simple addition to FileCheck syntax to improve error
messages in this case: a CHECK-UNIQUE directive which indicates that a
given check is a uni...

valid ticket? One of my favorite failures is when the time settings
between the local host, and the Samba or AD server, have drifted from
each other. There are a lot of very awkward and inconsistent NTP or
chronyd settings out there, exacerbated when people point NTP to only
one server and that server is inaccessible to one or more hosts.

server is not imap4 compatible
...15 to
1.0.15.
after the upgrade i was forced to enhance the
proc.sys.fs.inotify.max_user_instances = 1024
because i had error messages about "Inotify instance limit for user

my question is:
does the upgrade triggered a new way of communication between
clients and server that exacerbates the problem of dropped
connections from the DMZ server?
p.s.
the dovecot configuration is:

R CMD check dependency simplification
...e to make changes to
src/pkg1/man/foo.Rd and have dependencies that indicate only codoc and
examples need to be re-run, not tests and vignettes. (R CMD check can to
do this, the problem is moving the appropriate new pieces, in the
appropriate way, into the pkg1.Rcheck directory.)
The difficulty is exacerbated for me because I have pkg3 depends on pkg2
depends on pkg1. If I make a change to src/pkg1/inst/doc/guide.tex then
I really should only need to re-do the vignettes for pkg1, but instead I
have to re-do the whole "R CMD check" for pkg1, pkg2, and pkg3.
Suggestions would be appreciated....

Vanished Files issue/enhancement
...is working extremely well. We've already done an emergency failover
to the warm-backup servers with an acceptable amount of data loss -
mostly nothing!
I have found; however, a race condition exists between users and rsync
that causes a 'vanished file' error. This race condition is exacerbated
when the link speed between the systems is slow such as a T1.
rsync -avpozO -e ssh /somedirectory/ backupserver:/somedirectory/
During normal system operation, users are allowed to delete files that
they own in 'somedirectory'. This is especially true in /home. When
rsync is instanti...

So sorry! was: Re: EL 6 rollout strategies? (Scientific Linux)
...frustration is at a high point as a result of these combined factors, causing
many involved to question even the very best of decisions.
I suspect that the many requests for ETAs are exacerbating the issue that the
CentOS developers simply cannot predict a final release date, which is further
exacerbated by the otherwise noteworthy, high-quality QA now in place, which
is causing requests for build changes that delay the release and cause need
for further QA checks on packages rebuild due to deps changes.
It's a perfect storm of factors that, together, result in the current
situation. I...

The easiest way to do this might be to look at the maximum of the
covariance of the input/output, or find the phase offset of the input
and output FFTs. Maybe it already does this, and someone can say if so?
P.S. The above situation is almost exactly what happens on my Mac,
and would be exacerbated by people with third party sound cards.

[LLVMdev] calling conventions and inlining
...TOH, does a
large amount of IPO and IPA, such as dead argument elimination, IPSCCP,
and other things. Something that is good to inline for GCC is not
necessarily good for LLVM.
3. Once these annotations are added to a source base, they are almost
never removed or reevaluated. This exacerbates #2.
In my mind, the right solution to this problem is to use profile-directed
inlining. If you actually care this much about the performance of your
code, you should be willing to use profile information. Profile
information will help inlining, but it can also be used for far more than

Frequent metadata corruption with ext3 + hard power-off
Hello.
I'm having serious issues with ext3; any insight would be greatly appreciated:
_____ Overview:
I believe ext3 is supposed to be recoverable in the case of a power failure by
replaying the log.
However, on two separate computers (running different operatings systems too),
this has been everything but the case.
_____ Specifics:
Sometimes, my kernel will hard-freeze and I'll

GEP with a null pointer base
...is contrary to the essentially universal software engineering
practice of writing software that is compiler warning free, static
analyzer warning free, and dynamic analyzer warning free.
This is based on the assumption that in order for llvm to be useful to its
users it should mitigate rather than exacerbate the problems inherent
in the language w.r.t. UB.
No one is debating in this thread what the standard does or should say.
After suggesting that the user should have an opt-in option for deleting
UB it was suggested that this would be awkward to implement in llvm.
I disagree, but it seems that the...
